Abstract (en)
[origin: EP0949026A1] A thermal shock-resistant ceramic article and a method of manufacturing the article include alternating layers of a first material (2) comprising a fusible, particulate ceramic composition and a second material (3), typically comprising a porous, pyrolyzable material. The layered structure increases the article's work of fracture and toughness, and may lead to improved thermal shock-resistance. The method advantageously uses a sheet, film or sleeve to prepare the article for firing. The composition, thickness, and porosity of the second material (3) will affect the desired properties. The method is particularly adapted for manufacturing cylindrical articles, including stopper rods, nozzles, and pouring tubes for the metal casting industry. <IMAGE>
